The ST Internal Implant System is intended to be surgically placed in the maxillary or mandibular arches for the purpose providing prosthetic support for dental restorations (Crown, bridges, and overdentures) in partially or fully edentulous individuals. It is used to restore a patient's chewing function. Smaller implants (less than 6.0 mm) are dedicated for immediate loading when good primary stability is achieved and with appropriate occlusal loading. Larger implants are dedicated for the molar region and are indicated for delayed loading.
The ST Internal Fixture is a substructure of a dental implant system made of CP Ti Grade 4 with the surface treated by SLA method. The abutment is a superstructure of a dental implant system which is attached to the implants made of Ti-6A1-4V ELI with the surface treated by anodizing method(except healing and temporary abutment). The ST Internal Implant System is intended to be placed in the upper or lower jaw to support prosthetic devices, such as artificial teeth, and to restore a patient's chewing function. The system is consisted of the following components: ST Internal Fixture, EZ Post Abutment, Solid Abutment, Angled Abutment, Milling Abutment, Cover Screw, Healing Abutment, Temporary Abutment, and Abutment Screw.
The provided text is a 510(k) summary for the ST Internal Implant System. It does not describe a study to prove the device meets acceptance criteria in the traditional sense of a clinical trial or performance study with defined acceptance criteria for accuracy, sensitivity, specificity, etc.
Instead, this document focuses on demonstrating substantial equivalence to predicate devices. Substantial equivalence for a medical device is established by showing that the new device (subject device) is as safe and effective as a legally marketed device (predicate device) that is already cleared by the FDA. This is typically achieved by demonstrating that the new device has the same intended use and the same technological characteristics as the predicate, or if there are differences, that those differences do not raise new questions of safety or effectiveness.
The "acceptance criteria" here are not performance metrics like sensitivity or specificity. Rather, the implicit acceptance criteria are that the differences between the subject device and the predicate(s) are minor and do not negatively impact safety or effectiveness, as demonstrated through non-clinical (bench) testing.
Here's a breakdown of the requested information based on the provided text:
1. A table of (implicit) acceptance criteria and the reported device performance:
| Implicit Acceptance Criteria (for Substantial Equivalence) | Reported Device Performance |
|---|---|
| Biocompatibility: Same material composition, manufacturing process, and patient-contacting parts as predicate. | The subject device (ST Internal Implant System) has the same material composition, manufacturing process, and patient-contacting parts as the predicate device (AnyRidge Octa 1 Implant System, K182448) for fixtures (ASTM F67) and abutments (ASTM F136). Therefore, no additional biocompatibility testing was required.Implied Pass |
| Surface Treatment: Same surface treatment and manufacturing process as predicate. | The ST Internal Implant System has the same surface treatment (S.L.A.) and manufacturing process as the predicate device (AnyRidge Octa 1 Implant System, K182448) for fixtures. Evaluated in accordance with 'Section 11 of Class II Special Controls Guidance Document'. Implied Pass |
| Pyrogen and Endotoxin: Meet regulatory requirements. | Will be conducted on every batch in accordance with 'Guidance for Industry Pyrogen and Endotoxins Testing: Questions and Answers'. (This is a commitment, not a prior test result for this submission). |
| Sterilization Validation & Shelf Life: Achieve sterility assurance level (SAL 10^-6) and validate proposed shelf life. | Sterilization validating testing performed according to ISO 11137 and ISO 17665-1, 2, verifying SAL 10^-6. Shelf-life tests conducted using accelerated aging (ASTM F1980) validated a 5-year shelf life. Implied Pass |
| Performance (Physical Properties): Withstand fatigue and loading under worst-case conditions. | Bench tests (static compression-strength test and fatigue test) performed in accordance with ISO 14801 and Class II Special Controls Guidance Document. Test results show the subject device is "better able to withstand the fatigue and loading" compared to the predicate device, despite minor size and feature differences. Implied Pass |
2. Sample sized used for the test set and the data provenance (e.g. country of origin of the data, retrospective or prospective)
- Test Set Sample Size: The document does not specify exact sample sizes (number of units tested) for the non-clinical bench tests (static compression-strength and fatigue tests). It mentions that tests were performed "with combination of the fixture and the angled abutment, in consideration of the worst case" and refers to ISO 14801. ISO 14801 typically involves testing a certain number of samples (e.g., n=10 or more) for fatigue and static strength for statistical validity, but the exact count is not provided in this summary.
- Data Provenance: The tests were performed by MegaGen Implant Co., Ltd. which is based in Republic of Korea. The data is non-clinical bench test data, not human subject data, so "retrospective or prospective" doesn't directly apply in the same way it would for a clinical study.
3. Number of experts used to establish the ground truth for the test set and the qualifications of those experts (e.g. radiologist with 10 years of experience)
- This information is not applicable as there was no study involving human expert interpretation or establishing ground truth based on expert consensus. The "ground truth" for non-clinical tests like fatigue and strength is based on physical scientific principles and engineering standards (e.g., ISO 14801).
4. Adjudication method (e.g. 2+1, 3+1, none) for the test set
- This information is not applicable as there was no study involving human interpretation or adjudication.
5. If a multi reader multi case (MRMC) comparative effectiveness study was done, If so, what was the effect size of how much human readers improve with AI vs without AI assistance
- No, an MRMC comparative effectiveness study was not done. This device is a dental implant system (physical product), not an AI diagnostic tool that assists human readers.
6. If a standalone (i.e. algorithm only without human-in-the loop performance) was done
- No, a standalone algorithm performance study was not done. This device is a physical dental implant system, not an algorithm.
7. The type of ground truth used (expert concensus, pathology, outcomes data, etc)
- For the non-clinical tests, the "ground truth" is defined by adherence to international standards and guidance documents like ISO 14801 and specific FDA guidance for root-form endosseous dental implants. This involves objective physical measurements (e.g., fatigue limit, static compression strength values) verified against predefined acceptable ranges or performance relative to a predicate.
8. The sample size for the training set
- This information is not applicable. The context is a 510(k) submission for a physical medical device (dental implant), not an AI/ML algorithm that requires training data.
9. How the ground truth for the training set was established
- This information is not applicable for the reasons stated above.

6. Indication for use:
The ST Internal Implant System is intended to be surgically placed in the maxillary or mandibular arches for the purpose providing prosthetic support for dental restorations (Crown, bridges, and overdentures) in partially or fully edentulous individuals. It is used to restore a patient's chewing function. Smaller implants (less than 6.0 mm) are dedicated for immediate loading when good primary stability is achieved and with appropriate occlusal loading. Larger implants are dedicated for the molar region and are indicated for delayed loading.

7. Basis for Substantial Equivalence
The ST Internal Implant System is substantially equivalent to the predicate device in terms of indication for use, technical characteristics and function. They are material and have similar design. The size range and design of the subject device slightly differ from the predicate device however it is very minor not affecting substantial equivalence.
In order to demonstrate the difference in design does not raise any new issues in safety and effectiveness, each performance test on the subject and predicate device have been performed to figure out the physical property(e.g. fatigue limit) with combination of the fixture and the angled abutment, in consideration of the worst case according to "ISO 14801:2007" and "Section 8 of Class II Special Controls Guidance Document: Root-form Endosseous Dental Implants and Endosseous Dental Implant Abutment". The test result shows that the subject device is better able to withstand the fatigue and loading.
Based on the detailed comparison charts below and test results provided in this submission, we conclude that the subject device is substantially equivalent to the predicate devices.

1. Similarities
- The subject device has the same characteristic for the following compared to the predicate/reference devices. Manufacturer, Indication for use, Material, Sterilization Method, Surface treatment, Implant-to-abutment
- connection, Principle of operation and Shelf life
Differences 2.
- The subject device has the different characteristic for the following compared to the predicate/reference devices. Diameter, Length and Feature -
3. Discussion for difference
- Diameter:
The diameters of the subject device are slightly different with predicate device however the subject device lies within the range of reference device excepting for diameter 3.7 can be covered with diameter 3.6 included in predicate device.
There is a minimal difference in the diameter but the substantial equivalence was demonstrated by the fatigue test stated below.
- Feature: -
The subject device has a same feature as a predicate/reference device excluding a thread pitch. A thread pitch(0.7mm) is added in subject device, however there is a just 0.1mm difference in screw pitch between 0.7mm and 0.8mm. It does not cause a matter in substantial equivalence since the size difference is very minor.
: In order to demonstrate the differences do not raise an issue in substantial equivalence, each fatigue test on the subject and predicate device have been performed to figure out the physical property(e.g. fatigue limit), with combination of the fixture and the angled abutment, in consideration of the worst case according to "ISO 14801" and "Class II Special Controls Guidance Document: Root-form Endosseous Dental Implants and Endosseous Dental Implant Abutment". The test result shows that the subject device is better able to withstand the fatigue and loading in spite of the size and feature differences.
In conclusion, the subject device is substantially equivalent to the predicate device since the differences are minor and theses have been identified via the fatigue test the differences do not impact substantial equivalence.

Discussion for difference 3.
- Diameter and Total Height:
- The diameter and total height range of the subject device is slightly different with predicate/reference device however it does not cause a matter in substantial equivalence since the size difference is very minor.
- Surface Treatment: -
- The other difference is in surface treatment but we already presented multiple predicate/reference devices for anodizing in the other component comparison charts.

8. Summary of Non-Clinical Testing
The non-clinical testing data which are submitted, referenced, or relied on in this submission support demonstrating substantial equivalence.
Biocompatibility
The biocompatibility evaluation has been performed in accordance with International Standard ISO 10993- 1, "Biological evaluation of medical devices - Part 1: Evaluation and testing within a risk management process". The additional biocompatibility testing is not required since the ST Internal Implant System has same material composition, manufacturing process and patient contacting parts as predicate device, AnyRidge Octa 1 Implant System (K182448) for fixtures(ASTM F67) and abutments(ASTM F136).
Modified Surface Treatment
The surface treatment evaluation has been performed in accordance with 'Section 11 of Class II Special Controls Guidance Document: Root-form Endosseous Dental Implants and Endosseous Dental Abutments - Guidance for Industry and FDA Staff'.
The ST Internal Implant System has same surface treatment and manufacturing process as predicate device, AnyRidge Octa 1 Implant System(K182448) for the surface treatment of S.L.A(Fixtures).
Pyrogen and Endotoxin Test
The endotoxin testing will be conducted on every batch for the subject device in accordance with 'Guidance for Industry Pyrogen and Endotoxins Testing: Questions and Answers'.

§ 872.3640 Endosseous dental implant.
(a)
Identification. An endosseous dental implant is a prescription device made of a material such as titanium or titanium alloy that is intended to be surgically placed in the bone of the upper or lower jaw arches to provide support for prosthetic devices, such as artificial teeth, in order to restore a patient's chewing function.(b)
Classification. (1) Class II (special controls). The device is classified as class II if it is a root-form endosseous dental implant. The root-form endosseous dental implant is characterized by four geometrically distinct types: Basket, screw, solid cylinder, and hollow cylinder. The guidance document entitled “Class II Special Controls Guidance Document: Root-Form Endosseous Dental Implants and Endosseous Dental Implant Abutments” will serve as the special control. (See § 872.1(e) for the availability of this guidance document.)(2)
Classification. Class II (special controls). The device is classified as class II if it is a blade-form endosseous dental implant. The special controls for this device are:(i) The design characteristics of the device must ensure that the geometry and material composition are consistent with the intended use;
(ii) Mechanical performance (fatigue) testing under simulated physiological conditions to demonstrate maximum load (endurance limit) when the device is subjected to compressive and shear loads;
(iii) Corrosion testing under simulated physiological conditions to demonstrate corrosion potential of each metal or alloy, couple potential for an assembled dissimilar metal implant system, and corrosion rate for an assembled dissimilar metal implant system;
(iv) The device must be demonstrated to be biocompatible;
(v) Sterility testing must demonstrate the sterility of the device;
(vi) Performance testing to evaluate the compatibility of the device in a magnetic resonance (MR) environment;
(vii) Labeling must include a clear description of the technological features, how the device should be used in patients, detailed surgical protocol and restoration procedures, relevant precautions and warnings based on the clinical use of the device, and qualifications and training requirements for device users including technicians and clinicians;
(viii) Patient labeling must contain a description of how the device works, how the device is placed, how the patient needs to care for the implant, possible adverse events and how to report any complications; and
(ix) Documented clinical experience must demonstrate safe and effective use and capture any adverse events observed during clinical use.
